R2 increased an average of 77 per cent and accounted for 54, 59 and 58 per cent of the variations in yields when the four new factors were added to the model. These results have encouraged further efforts to develop a modified version of the PI model that uses computerized databases for ...
"HL" means that areas with grain production above the average are surrounded by areas with grain production below the average. There are obvious HH agglomeration characteristics in grain yields in the Shandong west plain and Jiaolai Plain regions, both of which are traditional agricultural areas wit...

For the county of grain production in Henan, the way to ensure the total amount of food is nothing more than two, the first guarantee that the number of cultivated land is not reduced, and second, to ensure that grain yields increased. At present, Chinese grain yield has made great ...
Towards Charlemont there is much bog, which yields red ashes, and is easily reclaimable; the substratum of this is a rich limestone. The eastern part of the county consists of a light friable soil. In the south the country is rocky and barren: huge rocks of granite are found on the ...
"The yields have been really good and the test weights have been good, so far," McClerren said. "We'd like to think we'll be done by the end of the month, if the weather gives us the chance." Timely wheat harvest is important for McClerren and many other growers in southern ...
